That sounds like some decent information. Shame about the website downtime though. What ended up happening is that I decided to attempt to decharge the battery by firing the gun. It died after cycling maybe 20 times. Then I hooked it up to the charger, which you can see from the images is not a $25 wallwart. This one was $100 from DEA. Took about an hour, and since then I've played in three games. It seems to be working just fine.
Thanks for the responses, despite their tardiness!
